16-port PCI-e RAID Controller - IOP341 / 256MB Cache (Upgradable to 2 GB)
4x Internal MiniSAS (SFF-8087) Ports / No Cables

ARC-1231ML/1261ML/1280ML/1280
(12/16/24-port PCIe to SATA ll RAID Adapters)

Areca high-performance PCI-Express bus to SATA RAID host adapters support 12, 16 and 24 SATA ll peripheral devices on a single host adapter. SATA RAID controller has the same RAID kernel of its field-proven external RAID controllers. Applications that benefit most features from these controllers including NAS, server RAID solutions, web server, supercomputing, near-line backup, security systems and streaming and streaming applications server.

The ML version comes with Min SAS 4i internal connector. This Min SAS 4i (SFF-8087) connector has eight signal pins to support four SATA drives and six pins for the SGPIO (Serial General Purpose Input/Output) side-band signals. The SGPIO bus is for efficient LED management and for sensing drive locate status, without any discrete fault & activity cable needed.
